194: Chapter 194 Assessment and Testing

Returning to the laboratory, Chen Youhua immediately summoned Wang Zhe and Li Wei.

"The military evaluation team will arrive soon," he said concisely, his gaze sweeping over Wang Zhe and Li Wei.

"The focus of this evaluation will be on the authenticity of the data, the standardization of the procedures, and the reliability and reproducibility of the final results.

All raw data, experimental records, and analysis reports must be ensured to be accessible at any time and logically closed-loop. The animal models and test platforms used for verification must also be maintained in their best state."

"This is the final test of all our past work, and it is the most critical step toward pre-clinical trials. Be rigorous and accurate."

"Understood!" The two spoke in unison, their expressions grave and focused.

No further mobilization was needed; the entire laboratory immediately began operating at high speed to conduct final self-checks and preparations.

The military's efficiency was unexpectedly high.

The next morning, a seven-member expert evaluation team arrived at the A-705 Laboratory, personally accompanied by Chief Zhang Guangdong.

Academician Zheng did not come, and Chen Youhua was a bit puzzled that Old Zheng was so busy?

The members of the evaluation team were of varying ages, but each had sharp eyes and a capable demeanor, covering multiple fields such as biomedical engineering, neuroscience, clinical medicine, materials science, and even military equipment reliability.

They were dressed in plain clothes, but their behavior and demeanor exuded a rigor and efficiency unique to soldiers.

Chen Youhua greeted Chief Zhang and his party at the entrance.

"Chief, welcome." He greeted them simply, without too much small talk.

Chief Zhang nodded with a smile.

"Professor Chen, no need for formalities. We are here today to be students, to listen and observe. The experts' questions might be a bit direct, just respond as usual."

His attitude seemed very peaceful, but when his gaze swept across the laboratory, it carried a scrutinizing tone.

Chen Youhua nodded slightly, then signaled to Wang Zhe and Li Wei.

"These two are the specific project leads, Dr. Wang Zhe and Dr. Li Wei. They will be in charge of the upcoming technical report and on-site inspection."

He did not choose to take the lead himself, but stepped back and stood side-by-side with Chief Zhang in the observation area.

This was a test for Wang Zhe and Li Wei, and besides, this technology did not depend on him alone, but was realized by these mature and reliable Researchers.

The evaluation officially began.

The military experts were clearly well-prepared.

Their questions were extremely professional and in-depth, pointing directly to core technical details and potential risk points.

A biomedical expert wearing gold-rimmed glasses carefully reviewed the long-term biocompatibility report provided by Li Wei.

"You mentioned in your report that in the final stage of degradation of the modified silk fibroin scaffold, there will be slight fluctuations in local amino acid concentration. How do you ensure that this fluctuation will not trigger uncontrollable immune responses or affect the microenvironment of nerve regeneration?"

Li Wei answered calmly, bringing up the corresponding monitoring data and high-resolution microscopic imaging.

"We verified this through in vitro simulations and extensive in vivo experiments. The fluctuation range is always within the regulatory capacity of the physiological buffer system.

More importantly, we observed that nerve axon regeneration at this stage has basically been completed, forming a self-stable microenvironment, and the dependence on scaffold degradation products has been significantly reduced. No chronic inflammation or rejection reactions caused by this have been observed in any of the experimental animals."

On the other side, an expert in charge of reliability engineering threw a series of questions at Wang Zhe.

"You claim that the system has extremely high robustness. May I ask if, in your tests, you have simulated composite extreme environments of extreme electromagnetic interference superimposed with mechanical vibration? How is the degradation mode of the control system designed? Will a single sensor failure lead to a chain collapse of the entire system?"

Wang Zhe took a deep breath and guided the expert to look at the real-time demonstration platform.

"We simulated a total of seventeen composite interference scenarios. These are the test logs and system response records from that time. Our system architecture is a distributed fault-tolerant design, with built-in multiple redundancy checks and anomaly isolation mechanisms.

A single node failure will automatically trigger a degraded operation mode, prioritizing the protection of core grasping and basic movement functions, and immediately reporting the fault information. A total collapse will never occur..."

The evaluation process was tense and efficient. The experts not only carefully checked the paper documents but also insisted on seeing the experimental animals with their own eyes.

They gathered in front of the observation window of several rhesus monkeys equipped with the latest generation of prosthetic limbs.

At this time, the prosthetic limbs were no longer the slightly clumsy mechanical arms from the New Year's Day demonstration.

Through deep cooperation with top prosthetic manufacturing companies, Wang Zhe's team perfectly combined bionic design, lightweight materials, and a powerful neural regulation core.

The silver-gray streamlined shell wrapped around the precise transmission structure, the finger joints moved flexibly and quietly, and the surface treatment was delicate, making it almost indistinguishable from traditional high-end prosthetic limbs.

Until it started to move.

At the signal of the experimenter, the monkey was seen climbing back and forth in a scene artificially imitating a forest in Nature.

The movements were smooth and natural, the power transmission had no sense of lag, as if it were a part of its body.

Only the faint blue indicator light that occasionally lit up when the prosthetic limb was working revealed its inherent technological content.

"The semi-automated connection platform ensures the stability and low latency of signal transmission," Li Wei explained to the experts observing carefully from the side.

"And the customized bio-mechanical interface provides long-term stability and biocompatibility. You can compare the range of motion and precision of its arms on both sides; the difference is already very small."

Several military experts gathered very close, with some even recording the muscle state and behavioral reactions of the animal's limbs, exchanging opinions in low voices from time to time, their faces gradually revealing undisguised admiration and approval.

Chief Zhang stood beside Chen Youhua, watching this scene with his hands behind his back, nodding slightly, and said in a low voice.

"Professor Chen, you have done even better than described in the report, especially this team; they are young, but very solid and professional."

Chen Youhua's gaze remained on the evaluation scene, and he responded with a smile.

"This team is the cornerstone of the entire project's successful completion."

The entire audit process lasted a full day.

When it ended, although the experts from the evaluation team looked tired, their eyes were filled with satisfaction and excitement.

The team leader, an old expert with gray hair but high spirits, made a concluding speech on behalf of the evaluation team. He looked at Wang Zhe and Li Wei, his tone very firm.

"The data is solid, the procedures are standardized, and the results are impressive. You have not only solved the core problems of biocompatibility and signal regulation, but you have also considered the system's engineering and reliability design very thoroughly, far exceeding our expectations. We will report this evaluation truthfully and positively to our superiors."

Chief Zhang finally stepped forward and shook hands firmly with Chen Youhua.

"Professor Chen, wait for good news. Next time, it will be our soldiers' turn to personally experience this piece of science fiction becoming reality."

His smile was full of expectation and trust.

After sending off the evaluation team, the laboratory quieted down.

Wang Zhe and Li Wei let out a long sigh of relief and smiled at each other.
